[Q] Atrix 4G Black Home screen no Menu

Atrix rooted ,have a titanium back up .
After a factory reset no home screen and no access to Menu & settings
I am looking for a way to put the USB port in debug mode without access to the settings.
After that reload the APK's (with Android Injector)and do a restore with Titanium

I was using launcher pro ,anyways all the problems appeared after the factory reset ,I can go to the google play APP store and I can see my download history
but cannot install APK's (Astro, Launcher ,etc) This is the message I get from Google play
“You haven’t accessed the Google Play Store app (the white shopping bag app icon) on your device with this email account

Any way to get in console mode and type a command line to enable the USB port
in debug mode

Blur account set up ,wireless working I can access google via voice command by pressing the search button.Again I have no way to reinstall the lancher Astro,and TiBu that is why I am trying to get the USB port in debug mode.
Anyone with a better plan ???
